Here are properties I have found with this:
Having a function [math]f(x)=x^{n}[/math], where n > 1.
with , it will require an infinite amount of steps to reach 2x.
Having a function [math]f(x)=x^{n}[/math], where n = 1 the amount of steps needed(conjecture) will be finite.
Having a function [math]f(x)=x^{n}[/math], where n = 0 the result will only be 0.
Having a function [math]f(x)=x^{n}[/math], where n = -1 the amount of steps needed(conjecture) will be finite because this would result in having the inverse multiplied by its normal function.
Having a function [math]f(x)=x^{n}[/math], where n < -1 the amount of steps needed(conjecture) will be infinite because this would result in having the inverse multiplied by its normal function...with , it will require an infinite amount of steps to reach 2x.
Here is a number line representing the properties:
Where p is the finite value(by the conjecture) by conjecture.
EDIT: Of course, these properties only apply if there are no other constants or variables in the equation.
EDIT2: So, I tried with negative values of n of x^n+1, more specifically -1, and currently it is giving very ugly results. I am still trying to see if it ever gets to 2x.
EDIT3: Turns out that if n of rx^n + c is less than -1 then the result goes onto infinity. There was a miscalculation. I am going to retry the calculations.
